This code worked for me last time I checked, but it was only intended
for Firefox. It will dispatch a click event on the element your give
it. If it's an anchor element and the event isn't canceled somewhere,
it will follow the link normally. I just pasted this in from a
project of mine. In hindsight, I should have checked and made sure
the anchor element had an href attribute before trying to go to it.
function mouseEvent(parent, type) {
var evt = parent.ownerDocument.createEvent('MouseEvents');
evt.initMouseEvent(type, true, true,
parent.ownerDocument.defaultView, 1, 0, 0, 0, 0, false, false, false,
false, 0, null);
return parent.dispatchEvent(evt);
}
function click(parent) {
return mouseEvent(parent, 'click');
}
function clickLink(target) {
var notCanceled = click(target);
if(target.tagName=="A" && notCanceled) window.location.href =
target.href;
}
To use:
var link = document.getElementById("...");
clickLink(link);
